How to insert SEI message info into H264 stream?

Hello,

You could check the h264enc user guide. You could find it here:

ezsdk/component-sources/omx_05_02_00_48/src/ti/omx/docs

Control for Configurable NALU

SEI (bit 6): This bit control the insertion of following SEI messages in video sequence. For details of these SEI messages refer Appendix D of H.264 standard
-timing_info_sei
- buffering_period_sei: This SEI is put only at IDR frames even if it is enabled for other positions in video sequence
-stereo_video_info_sei :This SEI is put only when stereoInfoPreset is enabled
If you want to encode with rateControlPreset == IVIDEO_NONE then nal_hrd_parameters_present_flag and vcl_hrd_parameters_present_flag will be false. Hence, buffering period SEI message will not be present.

The tStaticParam.videoStaticParams.h264EncStaticParams.nalUnitControlParams.naluControlPreset  should be set as IH264_NALU_CONTROL_USERDEFINED.

Best Regards,
